We´ve been trekking the backside of Torres del Paine and are about to embark on the W now. 7 days in, and about 4 to go. Yes, we are looking to spend an extra day or so here, because it is absolutely spectacularly mind-blowing to hike here.
As for the "holidays" it looks like Chile is the big winner. We´re trying to get on a 4-day boat trip from Puerto Natales to Puerto Montt to arrive there on the 24th. Then do a bit of hiking in that part of the world before making our way to Vina del Mar / Valparaiso for New Years. There´s a beach there, albeit a pacific ocean one (not so warm, but gorgeous!)
Internet access is sparse for us - WiFi is everywhere but no computers ... borrowed this one in a refugio. So talk to you in a few days again.
